Treatment of Expansion Joints

Expansion joints are installed to manage the coefficient of thermal expansion over large spans of concrete. The waterproofing material must not only cope with the movement of the building, but also be designed to resist aging that leads to the weakening of the bond on the concrete and causes failure of the system.

A flexible material is essential so that it does not crack with movement.

We offer a flexible and highly durable tape for expansion joints with high elasticity to accommodate the thermal movement and, at the same time waterproofing the leakage prone joint.

1Reinforced cement concrete (RCC) slab
2Apply 1st coat of PoxyFix
3Press the Expansion Joint Tape on top of the 1st coat of PoxyFix (Place the joint tape over the joint in such a manner ensuring that the central section dips into the joint)
4Apply 2nd coat of PoxyFix
5Fix the metal flashing to protect the tape
Note: The tape to joint is made using silicone based adhesive M 500
